3 Who being the brightness of His glory, and the express image of His person, and upholding all things by the word of His power, when He had by Himself purged our sins, sat down on the right hand of the Majesty on high;
Who is “who”? The previous verse states that it is the Son. So we know that this verse is referencing Jesus. He is the brightness or radiance of God’s glory. He is the exact image of God. The Greek word is “charaktēr” from which we get our English word “character.” Jesus has the exact character of God.
When Philip wanted Jesus to show him the Father, Jesus told him, “Have I been so long time with you, and yet have you not known Me, Philip? he that has seen Me has seen the Father; and how say you then, Show us the Father? (John 14:9)”. This is an amazing statement. It tells me that if you want to know what God is like, look at Jesus.
Jesus is the creator and sustainer of all things. He is carrying, upholding, and bearing all things—remember all means all. He does so by the word of His power. This is the dynamite infused rhema words of Jesus that holds all things together.
When He had purged our sins or when He had cleansed and washed away our sins, He finished His work on earth. From the very beginning the announcement was clear that Jesus came for one important purpose. “And she shall bring forth a son, and you shall call His name JESUS: for He shall save His people from their sins” (Matthew 1:21).
This seems to be one of the most contentious points for Christians. He purged our sins. He washed them away by the His blood. This is a once for all time event. He washed all sins away and He will remember then no more. He either washed them away or He didn’t. He didn’t wash away some but not others. He didn’t just wash away the sins we confess. He purged our sins and sat down next to the Father. The sin problem is over. We don’t have to confess sins. We don’t have to sin. Sin has no bearing on our relationship with God. PTL.
